Object. The goal of this study was to confirm the effectiveness of our novel treatment strategy, neoadjuvant therapy (NAT) consisting of combined chemo- and radiotherapy, which are performed before complete excision of residual tumor in patients with intracranial nongerminomatous malignant germ cell tumors (NGMGCTs). Methods. The authors treated 11 consecutive patients with NGMGCTs by applying NAT consisting of combined platinum-based chemotherapy and radiotherapy, followed by complete excision of residual tumors. The pretreatment diagnosis, based on tumor markers with or without biopsy, was yolk sac tumor in five patients, embryonal carcinoma in one patient, immature teratoma in one patient, and mixed germ cell tumor containing malignant tumor components in four patients. Among the 11 patients, NAT achieved a complete response in two and a partial response in six patients; two patients manifested no change and one suffered disease progression. Residual tumors that occurred post-NAT were surgically removed in nine patients. Of the 11 patients, 10 are currently alive without recurrence of their disease, 30 to 177 months (mean 96 months) after diagnosis. In one patient a leptomeningeal tumor recurred and he died of the disease 21 months after diagnosis. Conclusions. Neoadjuvant therapy, consisting of combined chemo- and radiotherapy, followed by complete excision of residual tumors is highly effective in patients with intracranial NGMGCTs.

Object The authors evaluated the effectiveness of a neoadjuvant therapy (NAT) consisting of combined chemoand radiotherapy followed by complete resection of the residual tumor in patients with nongerminomatous malignant germ cell tumors (NGMGCTs). Methods The authors treated 14 consecutive patients in whom NGMGCTs were diagnosed based on elevated levels of the tumor markers α-fetoprotein, human chorionic gonadotropin, and the β-subunit of human chorionic gonadotropin (β-HCG). Chemotherapy and radiotherapy were performed, and after the serum tumor markers level was in the normal or near-normal range, the residual tumors were completely resected. Results Residual tumors were confirmed in 11 of the 14 patients after NAT, and total removal was successful in 10 of the 11 patients. In the other patient the residual tumor could not be completely excised because it was attached to a deep vein. The follow-up duration ranged from 1.2 to 22.2 years. The 5-year event-free and total survival rates were 86% and 93%, respectively. Although 3 patients died, 2 of tumor recurrence and 1 of a radiation-induced secondary tumor (glioblastoma), the other 11 are alive and without evidence of tumor recurrence. Conclusions The authors consider their NAT protocol for NGMGCT to be highly effective in relation to survival for the patients with NGMGCT, but there are several quality of life issues that need to be resolved.

Abstract BACKGROUND: The role of second-look surgery in intracranial germ cell tumors (GCTs) needs to be reviewed. OBJECTIVE: To present our experience of second-look surgery in patients with intracranial GCTs who showed less than complete response despite normalizing or decreasing tumor markers after chemotherapy. METHODS: Retrospective review of 7 patients who underwent second-look surgery for an intracranial GCT was performed. RESULTS: Of 23 consecutive patients with newly diagnosed intracranial GCTs treated between August 2003 and August 2013, 7 patients (30%) underwent second-look surgery. The mean age was 9.4 years. The initial diagnoses were mixed germ cell tumor in 5 and immature teratoma in 2. Second-look surgery was performed after 1 to 3 courses of chemotherapy. Magnetic resonance imaging at the surgery demonstrated increasing residual tumor in 4 and stable residual tumor in 3. Tumor markers were normalized in 5 and nearly normalized in 2. Gross total resection was achieved in all patients. Histopathology at second-look surgery revealed mature teratoma in 5, fibrosis with atypical cells in 1, and fibrosis in 1. All patients subsequently underwent additional chemoradiation therapy according to the initial diagnosis. All patients are alive with no evidence of recurrence, with a mean follow-up of 48 months. CONCLUSION: Second-look surgery plays an important role in the treatment of intracranial GCTs. Surgery may be encouraged at a relatively early phase after chemotherapy when the residual tumor increases or does not change size despite normalized or nearly normalized tumor markers in order to achieve complete resection and improve outcome.

Object. To determine the pathogenesis of intracranial germ cell tumors (GCTs), the author studied 153 cases of these tumors encountered through 1994, 62.7% of which showed monotypic histological patterns and 37.3% of which were shown to be mixed tumors.Methods. Six patients died soon after admission and underwent autopsy; the other patients underwent surgery followed by radio- and/or chemotherapy. One hundred thirty-four cases were followed through the end of 1997. All patients with a choriocarcinoma died within 1 year. Patients with a yolk sac tumor (endodermal sinus tumor) or an embryonal carcinoma also had poor outcomes. Patients with a mature teratoma had 5- and 10-year survival rates of 93% each. Patients with an immature teratoma had 5- and 10-year survival rates of 86% each, whereas patients who had a teratoma with malignant transformation had a 3-year survival rate of 50%. Patients with a germinoma had a 5-year survival rate of 96% and a 10-year survival rate of 93%. These results may bring into question the validity of the germ cell theory because germinoma, which should be the most undifferentiated tumor according to the theory, was the most benign and choriocarcinoma and yolk sac tumor (endodermal sinus tumor), which should be the most differentiated tumors, were the most malignant according to results obtained during the follow-up study.Conclusions. Germ cell tumors other than germinomas may not originate from one single type of cell (primordial germ cells). The embryonic cells of various stages of embryogenesis may perhaps be misplaced in the bilaminar embryonic disc at the time of the primitive streak formation, becoming involved in the stream of lateral mesoderm and carried to the neural plate area to become incorrectly enfolded into the brain at the time of neural tube formation. The author propounds the following hypothesis: tumors composed of cells resembling the cells that appear in the earlier stages of embryogenesis (ontogenesis) are more malignant than those composed of cells resembling the cells that appear in the later stages of embryogenesis.

Cancer of the testis is a relatively uncommon disease, accounting for approximately 1-1.5% of all cancers in males.  5% of the malignant germ cell tumors are made of extragonadal origin. Germ cell tumors occur in men younger, usually between 20 and 35 years old. We report a case of a patient with metastatic extragonadal germ cell tumor with multiple sites of metastases, and very high initial values of tumor marker human chorionic gonadotrophin (HCG)- 1351308. At the time of diagnosis, the patient was in a very poor general condition. After the applied chemotherapy, there was a complete response and 7 years later the patient is without any symptoms of disease.

✓ The natural history of primary intracranial germ-cell tumors (GCT's) is defined from 389 previously published cases, of which 65% were germinomas, 18% teratomas, 5% embryonal carcinomas, 7% endodermal sinus tumors, and 5% choriocarcinomas. Intracranial GCT's display specificity in site of origin. Ninety-five percent arise along the midline from the suprasellar cistern (37%) to the pineal gland (48%), and an additional 6% involve both sites. The majority of germinomas (57%) arise in the suprasellar cistern, while most nongerminomatous GCT's (68%) preferentially involve the pineal gland (p < 0.0001). The age distribution of afflicted patients is unimodal, centering with an abrupt surge in frequency in the early pubertal years; 68% of patients are diagnosed between 10 and 21 years of age. Nongerminomatous GCT's demonstrate an earlier age of onset than do germinomas (p < 0.0001). Prolonged symptomatic intervals prior to diagnosis are common in germinomas (p = 0.0007), in suprasellar GCT's (p = 0.001), and among females (p = 0.02). Parasellar germinomas commonly present with diabetes insipidus, visual field defects, and hypothalamic-pituitary failure. Nongerminomatous GCT's present as posterior third ventricular masses with hydrocephalus and midbrain compression. Germ-cell tumors may infiltrate the hypothalamus (11%), or disseminate to involve the third ventricle (22%) and spinal cord (10%). Among a subpopulation of 263 conventionally treated patients, two factors were of prognostic significance: 1) histological diagnosis; germinomas were associated with significantly longer survival than nongerminomatous GCT's (p < 0.0001); and 2) staging of the extent of disease; this emphasizes the ominous character of involvement of the hypothalamus (p = 0.0002), third ventricle (p = 0.02), or spinal cord (p = 0.01). Specific recommendations regarding the necessity of histological diagnosis and staging of the extent of disease are made in light of modern chemotherapeutic advances. The pathogenesis of GCT's may be revealed by their specificity of origin within the positive (suprasellar cistern-suprachiasmatic nucleus) and negative (pineal) regulatory centers for gonadotropin secretion within the diencephalon. The abrupt rise in age distribution at 10 to 12 years suggests that the neuroendocrine events of puberty are an “activating” influence in the malignant expression of these embryonal tumors.

Object. Overexpression of the protooncogene c-kit has been suggested in a gonadal germ cell tumor (GCT). Recently, the soluble isoform of c-kit (s-kit) has been expressed in a variety of cell types. The goal of this study was to investigate the expression of c-kit and the clinical significance of s-kit in patients with GCTs. Methods. The authors first conducted an immunohistochemical investigation of the expression of the c-kit protein in 27 surgical specimens. In all 18 specimens that contained germinomas, c-kit was diffusely expressed on the cell surface of the germinoma cells, but was not found on lymphocytes or interstitial cells. In seven of eight immature teratomas, only some mature components, such as cartilage and glands, were immunoreactive for c-kit. Syncytiotrophoblastic giant cells (STGCs) demonstrated negative findings as well, suggesting that primarily germinoma cells express c-kit. Next, 47 cerebrospinal fluid (CSF) samples collected from 32 patients with GCTs (15 samples from patients with pure germinomas, 16 from patients with STGC germinomas, 14 from patients with teratomas, and two from a patient with a choriocarcinoma) were analyzed using a sandwich enzyme-linked immunosorbent assay. The level of s-kit was significantly higher in CSF collected from patients with germinomas and STGC germinomas than in CSF collected from patients with teratomas or non—germ cell brain tumors, or in CSF collected from controls. The concentration of s-kit in CSF was correlated with the patient's clinical course; it was significantly higher in pretreatment samples obtained before and in samples obtained at the time of tumor recurrence than in samples collected from patients in whom the tumor was in remission. The level of s-kit was remarkably high in CSF collected from patients with subarachnoid tumor dissemination. Conclusions. These results indicate that the concentration of s-kit in CSF may be a useful clinical marker for germinomas, especially for detecting recurrence or subarachnoid dissemination of these lesions.

✓ Primary intracranial germ-cell tumors are infrequently occurring neoplasms which most often arise in the pineal or sellar regions. Germinomas are seen more frequently than nongerminomatous germ-cell tumors; they are often curable with radiotherapeutic approaches, or with chemotherapy in the rare instance of extraneural metastasis. Nongerminomatous germ-cell tumors are relatively radioresistant and when extraneural metastasis has occurred, they have been fatal in all of the 32 previously reported cases. The case of a 14-year-old girl with a mixed malignant germ-cell tumor arising in the pineal region is reported. Extraneural metastasis to the lung developed 12 months after whole-brain radiotherapy was completed. She was treated with etoposide (VP-16), high-dose cisplatin, vinblastine, and bleomycin and is currently without evidence of disease 46 months postmetastasis.

10023 Background: The management of pediatric malignant germ cell tumors (MGCTs) includes induction therapy with 3-4 cycles cisplatin, etoposide, bleomycin (PEb). The current practice recommends 2-3 cycles of PEb (total 6 cycles) as consolidation therapy if response is not complete at the end of induction, a significantly different approach than that used in adult patients who receive a standard number of cycles. Furthermore, there is no evidence supporting the addition of a consolidation phase with PEb in pediatric patients with MGCTs. Methods: We retrospectively reviewed all patients enrolled in a phase III, single-arm trial for low-risk and intermediate-risk MGCTs (AGCT0132). All patients received 3 cycles of PEb and underwent response assessment at the end of induction. Complete Response (CR) was defined as negative tumor markers and no viable residual lesion. Patients in CR were not to receive any further chemotherapy. Patients not in CR were prescribed 3 additional cycles of PEb as consolidation. Event-free survival (EFS) and Overall survival (OS) was calculated using the Kaplan-Meier method. Results: Among 210 patients enrolled, 193 patients had CR after 3 cycles of induction chemotherapy, and their post-induction 4yr-EFS and OS was 93% and 99%. Fifteen patients were not in CR at the end of the first 3 cycles and received additional chemotherapy, and their 4yr-EFS and OS was 51% and 60%. Conclusions: Children with MGCTs who have a partial response after the first 3 cycles of chemotherapy had an inferior outcome compared to those with a CR, despite receiving additional cycles of PEb chemotherapy. Thus, we conclude that consolidation is of unclear benefit. Although our results are limited by small sample size and lack of comparator, we propose that pediatric MGCT patients who fail to achieve a CR after standard induction chemotherapy should receive a salvage regimen with different agents rather than consolidation with more cycles of the same chemotherapy.

10022 Background: Adolescents with extracranial malignant germ cell tumors (GCTs) are often treated on the same regimens developed for children, but more closely resemble the clinical characteristics of young adult patients. We sought to determine whether event-free survival (EFS) for adolescents with GCTs was more like that of children or young adults. Methods: We assembled an individual patient database of ten GCT trials: seven conducted by pediatric cooperative groups and three by an adult group. We selected male patients aged 0-30 years old treated with platinum-based chemotherapy for non-seminomatous malignant GCTs of the testis, retroperitoneum, or mediastinum. We categorized age-group as children (0 to < 11 years), adolescents (11 to < 18 years), or young adults (18 to < 30 years old). We compared EFS among age groups, and adjusted for calculated IGCCCG risk-group using Cox proportional hazards analysis. Results: 593 patients met inclusion criteria, of whom 90 were children, 109 were adolescents, and 394 were young adults. The 5-year EFS for adolescents (72%; CI = 62-79%) was significantly lower than for children (90%; CI = 81-95%, p = 0.003) and for young adults (88%; CI = 84-91%, p < 0.001). Risk-group was significantly associated with EFS in the adolescent age-group (p = 0.002). In a Cox multivariable analysis, the difference between adolescents and children remained statistically significant (HR = 0.30, p = 0.001), but the difference between adolescents and young adults did not (HR 0.66, p = 0.114). Conclusions: EFS for adolescent patients with extracranial malignant GCTs was similar to young adults but significantly worse than children. This finding may have important implications for how adolescent patients are treated.

✓ The authors analyzed 153 cases of histologically verified intracranial germ cell tumors. The histological diagnosis was germinoma in 63 patients (41.2%), teratoma in 30 (19.6%), and other types of tumors in 60 patients (39.2%). The patients were treated by a consistent policy of surgical removal with histological verification followed by radiation therapy with or without chemotherapy. The 10- and 20-year survival rates of patients with pure germinoma were 92.7% and 80.6%, respectively. The 10-year survival rates of patients with mature teratoma and malignant teratoma were 92.9% and 70.7%, respectively. Patients with pure malignant germ cell tumors (embryonal carcinoma, yolk sac tumor, or choriocarcinoma) had a 3-year survival rate of 27.3%. The mixed tumors were divided into three subgroups: 1) mixed germinoma and teratoma; 2) mixed tumors whose predominant characteristics were germinoma or teratoma combined with some elements of pure malignant tumors; and 3) mixed tumors with predominantly pure malignant elements. The 3-year survival rates were 94.1% for the first group, 70% for the second group, and 9.3% for the third group, and the differences were statistically significant. Twenty-six patients with malignant tumors received chemotherapy that consisted of cisplatin and carboplatin combinations with or without radiation therapy. However, chemotherapy was not significantly more effective than radiation therapy alone. From these treatment results, the authors classified tumors into three groups with different prognoses and proposed a treatment guideline appropriate for the subgroups.
